4 Claims. 1

This invention relates to a tool for inserting tie rods on building wall forms.

It is an object of the present invention to provide a quick attachable and detachable tool, adapted for connection to a tie rod whereby to locate the tie rod in a hole in the opposite form from which it is connected in order that the forms can be pulled or pushed and spaced properly from one another, and wherein the inserting tool can be readily released from the tie rod by a simple movement of the tool over the head of the tie rod.

It is another object of the invention to provide a quick attachable and detachable inserting tool for tie rods wherein the handle can be swung to a position in alignment with the pull cable so that the handle can be passed through an 'opening in a wall form.

the tool and with the member merely clamping the tie rod within the end of the inserting tool between locking and unlocking positions.

Other objects of the present invention are to provide a tie rod inserting tool for forms used in wall constructions which is of simple construction, easy to attach to the tie rod, inexpensive to manufacture, has a minimum number of parts, strong, durable and efficient in operation.

For a better understanding of the invention reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. 1 is a perspective view of the inserting tool connected to a tie rod with the handle extending transversely of the cable, and with the tie rod locked in place in the tool head.

Fig. 2 is a fragmentary enlarged sectional view, taken on line 2--2 of Fig. 1.

Fig. 3 is an enlarged collective and sectional view taken generally on line 33 of Fig. 1.

Fig. 4 is a fragmentary side elevational view of the head along the lines 4-4 of Fig. 3 with a portion broken away to show the tie rod in position within the head.

Fig. 5 is a transverse sectional view taken on line 55 of Fig. 3 showing the retaining sleeve adjusted in the head to receive the tie rod.

Fig. 6 is an enlarged perspective view of the retaining sleeve.

Referring now to the figures, [0 represents a head adapted to be connected to a tie rod l I having an enlargement I2 thereon retained by upsetting the end of the tie rod as indicated at l3. The tool further includes a cable l4 fixed to the head l0 and having a ball enlargement IS on its end. This cable is passed through a hole [6 in handle member I! and the ball I5 is retained in a socket opening l8. The handle is upset around the top of the socket opening I8 as indicated at 19 to retain the ball I5 within the handle. On the underside of the handle I! and extending through one end thereof is a slot 2| into which the cable It can pivot so that the handle can be aligned with the cable l4 and thus be drawn through an opening of the Wall together with the tie rod H which is then released from the head l0.

The forward end of the cable I4 is retained in a central opening or hole 22 in the head body and is turned in at its end as indicated at 23 to provide an enlargement to prevent the outward pull of the cable [4 from the head I 0.

The head has a hollow portion 24 with an end 25 thereon, serving as an abutment for a locking sleeve 26 that is used to retain the tie rod II in a longitudinal slot 21 communicating with transverse slot 28 intermediate the length of the hollow portion 24. The transverse slot 28 is adapted to receive the enlargement l2 on the tie rod and the tie rod itself can pass through the longitudinal slot 21 to fit in the retaining clip or sleeve 26.

The retaining sleeve 26 has opposing spring portions 29 and 30 with a slot 3| therebetween through which the rod ll passes. The spring portions 29 and 30 are flared outwardly at their outer ends so as to catch and retain the rod l I. If desired, the sleeve 26 can be rotated within the hollow portion 24 to make a more effective locking engagement of the rod relative to the longitudinally extending slot 21.

In order to provide shoulders against which the enlargement l2 of the rod H may engage, struck portions 32 and 33 extend inwardly and engage with the underside of the enlargement l2. These inwardly struck portions 32 and 33 will also retain the retaining sleeve 26 against axial displacement within the hollow portion 24 and to prevent it interfering with the transverse opening 28 and these inwardly struck portions may cooperate with recesses 30 and 35 on the end edge of the sleeve 26 to prevent it from turning or for limiting the amount of turning of the retaining sleeve 26 in the hollow portion 24.

It should be noted that a struck portion 36 in the head 24 prevents the tie rod H from moving longitudinally thereagainst, when said tie rod. I I is placed in proper operating position.

To make the insertion of the tie rod within the head, the enlargement l2 on the tie rod is first fitted in the transverse opening 28 and thereafter the tie rod is brought downwardly through the longitudinal slot 26 and into the end portion 25. The tie rod also passes into the retaining sleeve-26 and between the portions 29 and 30 which will retain the tie rod against lateral displacement from the head. It will be seen by being able to turn the handle I? into alignment with the cable I4 that the handlecan pass'along with the cable [4 and the head H] throughholes in the construction forms. When it is desired to remove the tie rod, this-can' be effected by a simple exertion of force to spring the-portions 2t and 38 of the sleeve :2'6 and to allow the rod to pass through the longitudinal slot 2 and the head outwardlyof the transverse slot 28.

While various changes may be made in the detail construction, it shall be understood'thatsueh changes shall be within the spirit and scope of the appended claims.

Having thus set forth and :disclosed the nature of my invention, what'is claimed is:

1. A tierod inserting tool adapted for connec tion with an enlarged head on a tie rod comprising a sleeve member having an'elongated notch extending vfromfthe attaching end thereof with a laterally downwardly and forwardly extending notch for receiving ahead on the tie rod, whereby to vpermit threaded 'movement of the head through the attaching sleeve member, saidllongitudinally extending'notch being'adapted to accommodate the tie rod and having a Width only slightly larger than the diameter of the tie rod and an end formation on the sleeve head member, and a retaining sleeve for the tie rod to retain the same within the longitudinal extending slot fitted'in the hollow sleeve member and abutting the end formation thereon, said retaining sleeve having inwardly extendingopposlng spring portions between which the 'rod'may pass and be retained against lateral displacement.

2. A tie rod inserting tool adapted forconnecsleeve being recessed on its end edge on the opposite sides thereof and said struck portions ex- 'tendinginto-the respective recesses and serving to retainnthe retaining sleeve against rotation within the sleeve member.

4. -Atie rod-inserting tool adapted for connection with an enlarged head on a tie rod comprising a sleeve member having an elongated notch extending from the attaching end thereof with a laterally downwardly and forwardly extending notch for receiving'a head on the tie rod, whereby "to'permit threaded movement of the head throughthe attaching sleeve member, said longi tudinally extending notch being adapted to accommodate the tie rod and-having a width only slightly larger than the diameter of the tie rod and an end formation on the sleeve head member, and a cable extending rearwardly from the tool head, said cable having a ball formation on the rear end thereof, a handle having a socket opening therein receiving said ball formation on the cable, said handle having a recess extending from the socket opening and through one end of the handle whereby the-handle may be pivoted to receive the cable andto'be in alignment there- 'with so that the'tool can'bepassedthrough ball openings or holes in the construction wall parts.
